Warn & error when npm start

[jack-cn]

Code to reproduce the issue:

npm start

Expected behavior:

no warning & error

Actual behavior:

  Replace Autoprefixer browsers option to Browserslist config.
  Use browserslist key in package.json or .browserslistrc file.

  Using browsers option can cause errors. Browserslist config 
  can be used for Babel, Autoprefixer, postcss-normalize and other tools.

  If you really need to use option, rename it to overrideBrowserslist.

ValidationError: Invalid options object. Sass Loader has been initialized using an options object that does not match the API schema.
 - options has an unknown property 'includePaths'. These properties are valid:

latest

It seems to be caused by the options change of sass-loader@8(options -> options.sassOptions), downgrading sass-load to 7.x.x solved this problem.
Try yarn add -D sass-loader@7.

$ npm install sass-loader@7 # remove error
$ npm install [email protected] # remove warning

This works in my environment.
